It's not clear that there should be a dedicated directory for installed
EPUB files, or that people would install lots of these.  I'm not too
clear on how people would use the EPUB output.

The 'docdir' in "(standards)Directory Variables" appears sufficient:

'docdir'
     The directory for installing documentation files (other than Info)
     for this package.  By default, it should be
     '/usr/local/share/doc/YOURPKG', but it should be written as
     '$(datarootdir)/doc/YOURPKG'.  (If you are using Autoconf, write it
     as '@docdir@'.)  The YOURPKG subdirectory, which may include a
     version number, prevents collisions among files with common names,
     such as 'README'.

htmldir, dvidir etc. all default to ${docdir} by default (with
autoconf/automake).  There would seem to be no benefit to
creating an epubdir along the same lines, in my opinion.
